I agree with everything said. I am 61 and on average have been on a diet every 3 years from the age of 20 (though had given up at about age 50). I was at goal (around 125) probably at least 5 times. I always regained and each time added more weight. This time I knew I had to do something different: I needed to have an additional tool. Overall this has been the best decision I ever made because not only have I lost the weight but am eating very differently and I am in great health (had high blood pressure, sleep apnea, high cholesterol and was pre-diabetic prior to surgery). And I have built-in portion control!
